MCHINE FOR HANDLING PAVING MATERIAL.

To all whom t may concern.'

Be it known that I, WALTERA. TRINLER, a citizen of the UnitedStates,.residing at Rutherford, in the county of ,Bergen and State ofNew Jersey, have invented certain new and useful Improvements inMachines for Handling Paving Material, of which the following is aspecification.

The present invention relates to a machine arranged and constructed forthe purpose of handling the blocks or bricks used in the construction ofpavements.

The objects of thepinvention are, to` provide an endless carrier adaptedto receive and transport paving bricks or blocks, which? endless carrierwill move in a horizontal plane and will remain, throughout its length,a uniform height from the ground level, which height will be proper toallow the workmen to remove the bricks from the conveyer while in thestooping position assumed in pavement laying; vto provide suitable meansfor driving the conveyer, and toy allow a reversal of the direction oftravel of the conveyer when desired; to provide a trackway upon whichthe conveyer travels; to provide tractor means for the 'framework; toprovide motor power for operating said tractor means; to providemeanspermitting of a reversing of the direction of movement of the tractormeans; and also to provide means permitting the tractormeans on one sideto be driven independently of the tractor means on the'other side andthus effect a steering of the machine.

The invention further consists in the features of construction andcombination of parts hereinafter described andv claimed.

In the art to which the present invention- Patented FebQlZ? 1917.

vnipulated, and can be built sufficiently cheap to warrant its adoptionby the contractor. Referring now to the drawings, the machine lcomprisesa framewo-rk 6, which, as shown, 'consistsof an upper section 7 and alower' section 8. Each of these sections is of angle-formation, as willbe seen more clearly from Fig. 3. lThe upper section has the angledportion 9 turned inward to form a frame along the inner edge of saidsection. The lower section has the angled portion 10 turned outward toform a trackway for the conveyer, which will be more fully hereinafterdescribed.V TheV two sections are connected vtogether in any suitablemanner, as, for instance, plates 1l.

Still referring to Fig. 3, it will be seen that the lower portion ofthis framework is open so that in fact the framework is of hollowconstructionV and open at its lower end. The function of this will morefully hereinafter appear. Suitable crossisupports 12'are provided, andto these cross supports aremounted wheels 13, which are ofa naturetodrive a caterpillar chain 14. There are two of these caterpillartractor wheels provided, one on each side, as will be seen from Fig. l.I prefer the use of this caterpillar construction because ofthe factthat it givesl abroad base for the tractor .members, so that they do notdepress or cut into the previously laid pavement.

yBy making the framework so that it is open at its lower end, I .canextend the tractor membersup inside of the frame. This allows the frameto be placed close to the ground, and will bring the conveyer at asuitable distance-probably about a foot from the ground vlinewhich isnecessary to allow the workmen to readily and quickly removethe blocksfrom the conveyer without moving from the stooped position assumed inypavement laying.

Upon the upper surface of the framel I provide, in the constructionshown, covering plates 15. The frame 6 as a Whole is made in two parts,one of which is designated by the numeral 16, and the other by thenumeral 17; and these parts Vare joined together, as shown, by a `boltedillerblock 18.

By loosening the bolts -of this filler block,v

the parts of the frame can be .moved with respect to one another so asto lengthen the frame orV shorten it, in correspondence to the width ofthe street being paved.

I employ, inthe construction shown, a gas vmotor 19 for driving thetractor members. The drive shaft of the motor is provided with a pinion20 meshing with'a gear 21, which drives a cross shaft 22. This crossshaft carries a pinion 23 moved in and out of driving engagement bymeans of a suitable clutch 24. The pinion 23 meshes with agear 25 on adriven shaft 26; and on this driven shaft is a sprocket 27 for driving achain 28 leading to the tractor on lone side. Also on the shaft 26 is asprocket 29 driving a similar chain 28 to actuate the tractor on theopposite side.

The sprocket 27 is thrown in and out of driving relation by means of aclutch 30, and the sprocket 29 is thrown in and out of driving relationby a clutch 31. By actuating the clutch 24, the entire drivingconnection `to both tractors is interrupted and the machine remainsstationary, although the engine is running. When both clutches 30 and 31are thrown into engagement, both tractor members are driven and theentire machine moved straight forward or back. However, if theV clutch30, for instance, is thrown into engagement and the clutch 31 out ofengagement, then only the tractor driven by the sprocket 27 will beactuated, which will effect a turning vof the machine in one direction.If the clutch 31 is thrown in and the clutch 30 out, the machine willthen be driven in the opposite directionV through the actuation of onlytheV tractor member associated with the sprocket 29. Of course, theparticular means of driving the tractors is subject to variation andmodification.

Mounted idly upon the shaft 22 is a gear 32 controlled by a clutch 33.This gear 32 meshes with a gear 34, which is secured to a shaft 34ahaving on its other end a gear 35, which meshes with the gear 25, and byvthis means a reverse motionV is imparted Vto the shaft 26 to effect areverse drive of the tractors.

The conveyer comprises a link belt or chain 36 of suitable construction,joined to which are a plurality ofplates 37 in overlapped relation.These plates are mounted so that they pivot about the pins 38, whichconnect them to the chains. This permits the conveyer to turn around thecorners of the frame. A U-shaped vmember 39 is secured to the plates andto the chain, which U-'shaped member serves as a mounting for a roller40 that travels on the flange 10 of the lower section of the frame. Thisflange, therefore, constitutes a trackway for the conveyer, whichprevents the conveyer from sagging during operation.

By making ltheconveyer of sectional formation, the length of it can beincreased or decreased in accordance with the shortening or lengtheningof the frame of the machine. The conveyer is driven by a series ofsprockets 41, which are mounted in bearings 42 within the frame. Asshown, there is one of these sprockets at each corner of the frame, andthe sprocket closest to the motor 19 (see Fig. 2) is driven by means ofa bevel gear 43 and bevel pinions 44 on a sleeve 44a which is mounted onthe shaft 22. By means of a lever 45, the position of the pinions 44 canbe shifted tobring one or the other into engagement with the gear 43.This enables a reversal to be made in the direction of travel of theconveyer. An adjusting mechanism 46 is shown. for one of the sprocketsto allow it to be moved in and out to take care of the slack which maydevelop in the conveyer.

From the foregoing, it will be apparent that the machine is cheap andsimple of construction for the work intended, and contains no involvednor complicated parts that would be liable -to become disarranged andplace the machine out of use. Also the bricks or blocks are deliveredclose to the ground within handy reach of the workmen, and-this isaccomplished lby mechanism which can be produced cheap enough to make itpractical of employment by the ordinary contractor.

'In' use, the machine is placed on the previously `laid pavement andmoved along as the work progresses. The sides of the machine are brought.close -enough'to the pile of bricks or blocks along the street toenable themto be placed on the conveyer of the machine, .by which theyare carried into position to be lifted olf by theworkmen and placed inposition@ rEhe various controlling Lmechanisms allow the machine to bemoved forward or backward, or around corners, and permit -fthe conveyerto be moved clockwise or counter-clockwise, as desired.
